Satan is not going to allow you to peacefully walk around in this life without hindrance. If you are going to be saved and your soul sanctified before the Lord and a passenger on the train to glory, then you are going to have to expel Satan from your life by attacking him directly.
Many of you where told that Satan or demons are not in the flesh when you come into a revelation of Jesus Christ and this is not true at all. You must understand that you are more complex then simply saying a sinners prayer and the Spirit of God comes into your life and you are done. Salvation is going to be a lot of work. David asked for God not to take his Spirit from him. Judas Iscariot cast demons out in Jesus name and later Jesus says to that same man, it would have been better that he was never born. You will have to fight to the very last day, if you want God to say after your death, well done.
Here is a great prayer to get started. Think of this prayer as a way to allow God to search your heart cleanse your body and give you some lightness for the next phase of strengthening yourself against the onslaught of evil principalities.
Pray this out loud:
Lord Jesus Christ. Search my body with your eyes. Look at the crown of my head and work your way down to the soles of my feet. Prepare my heart for the expelling of every demonic stronghold that is hindering me from my full power and potential in your kingdom. First bind the strongman inside of me. I ask for a thousand angels to be released from the third heaven to attack the spirit of lust, limitation, anger, fear, pride, arrogance, python, abandon, gargoyle, goblin, anxiousness, ocd, dreamer, unforgiveness, bitterness, blame, deception, doubt, confusion, memory loss, in Jesus name. Each and every evil spirit that I have named must be rounded up and expelled into the pit right now. Go into the pit you evil spirits by the power of God in Jesus name. Jesus, whatever license they have to remain, I ask for your forgiveness as I forgive anyone who has offended me, whether my father or mother, friend or sister or brother I forgive them. I forgive my enemy in Jesus name. Now every dark and evil spirit without authority inside me now go into the pit in Jesus name. Do not leave and enter my family, but angels send them into the pit directly in Jesus name. The strongman that is within now cast him out into the pit in Jesus name. Fill me with the Holy Spirits power and anointing as these spirits leave my body. Let God’s Holy Fire fill in the gaps that are created from the evil spirits leaving in Jesus name. I call for the buckets within the angels hands to pour in some joy, peace, and gladness. Pour in more love and more fire in Jesus name. My body is filling up with the anointed water from the third heaven in Jesus name. My cup is beginning to overflow in the name of Jesus. Thank you Lord for the overflow. Thank you Lord for the peace. Thank you Lord for the joy. My faith is increasing and my awareness of your grace, love, and ministering spirits. Amen.
